We will want to use the Pythagorean theorem
a^2 + b^2 = c^2
We can plug in the values we know
7^2 + 9^2 = c^2
49 + 81 = c^2
130 = c^2
We will then square both sides to get c by itself
c = 11.4 meters

Answer:

x = 97.6

Step-by-step explanation:

cos = adjacent over hypotenuse

cos(55)=\frac{56}{x}

* multiply each side by x *

cos(55)*x=xcos(55)\\\frac{56}{x} *x=56\\56=xcos(55)

* divide each side by cos ( 55 ) *

\frac{xcos(55)}{cos(55)} =x\\\frac{56}{cos(55)} =97.63302055

we're left with x = 97.63302055

Our last step is to round to the nearest tenth of a foot

We get that x = 97.6

erastova [34]

Answer:

Use this formula for these kinda things.

Step-by-step explanation:

Remember The z is the hypathonous, it means the biggest side.

{a}^{2}  +  {b}^{2}  =  {c}^{2}

where Z is going to be C

put this all together

{7}^{2}  +  {18}^{2}  =  {z}^{2}

put it into calculator, means 373=

{z}^{2}

therfore take the square root, it will be

z =  \sqrt{373}

which it will be 19.31
